Yeah, people often talk about scammers and grifters and how "insert-ableist-slurs" and "gullible" people who believe them are, but none of those "I'd ever fall for that!!1" types ever look at why people were so easily convinced, what large chunks of care are missing in society that people have no choice but to be drawn to the "alternatives" no matter how bogus or even dangerous - at some point the system has let you down so dramatically that even if it did finally offer a solution, you'd have no reason to trust it.
The result of which is instead of trying to better the system so that fewer people get treated poorly or not at all, they just shift the blame to those who fell victim to the scan, and can pat themselves on the back for being "better" without actually doing fuck all but ridicule vulnerable people.
People like that are just as much a part of the problem - the grifters give them someone to ridicule and feel superior to, they pander to the ego of the "unconvinced" as much as, if not more, than to the ego of the people they're trying to scam, giving that (ego boost) up even if it is to do the right thing (but in favour of those these individuals see as lesser) just doesn't make sense to them.
